COPENHAGEN, Denmark (AP) — The United Nations' expert panel on climate science on Saturday finished a report on global warming that the UN's environment agency said offers "conclusive evidence" that humans are altering the Earth's climate system.
The document, which combines the findings of three earlier reports, was adopted after all-night talks Saturday by the Intergovernmental Panel on Climate Change and is scheduled to be released to the public on Sunday.
Apart from discussing the human influence, it is expected to describe how climate impacts, including melting Arctic sea ice and rising levels, are already happening and could become irreversible unless the world curbs its greenhouse gas emissions.
The IPCC says scientists are now 95 percent certain that the buildup of such gases from the burning of fossil fuels and deforestation is the main cause of warming seen since the middle of the 20th century.
